Emergency Contraception: i-Pill vs Copper IUD in India

• Two main options in India: the levonorgestrel pill (i-Pill, Unwanted-72) for up to 72 hours, and the copper IUD inserted within 5 days (120 hours).
• The copper IUD is the most effective emergency contraception there is — over 99% — and its effectiveness does not fall off across the 5-day window.
• The pill is most effective in the first 24 hours (~85%) and weaker the longer you wait; take it as soon as you can.
• Emergency contraception is safe, does not cause abortion or infertility, and is sold over the counter for about 50-100 rupees.
• If you weigh over 80 kg / have a higher BMI, or it has been more than 72 hours, the copper IUD is the stronger choice.
• It is a backup, not a regular method — set up ongoing contraception soon after, and test for pregnancy if your period is more than a week late.

Emergency contraception is for any time you have had sex without effective protection and do not want to become pregnant. Common situations include:

You do not need to calculate whether you were in your fertile window. Cycles are unpredictable, and ovulation timing shifts — especially with irregular periods, in your teens, or approaching perimenopause. The safe approach is simple: if there is any chance of pregnancy and you do not want one, use emergency contraception rather than trying to guess your risk. The downside of using it when you maybe did not need to is small — a little nausea and the cost of a pill. The downside of skipping it is an unintended pregnancy.

Timing is everything, and the clock starts at the moment of unprotected sex. The levonorgestrel pill works up to 72 hours (3 days), best within the first 24. The copper IUD works up to 120 hours (5 days), with no drop in effectiveness across that window. If you are tracking with the cervical mucus method or another fertility-awareness approach and slipped up during your fertile days, that is exactly a moment emergency contraception is designed for.

The levonorgestrel emergency contraceptive pill is the method most Indian women know and reach for. It is a single 1.5 mg tablet of levonorgestrel, a synthetic progestogen. The familiar brands are i-Pill (Cipla) and Unwanted-72 (Mankind), both sold at any pharmacy for about 50-100 rupees, no prescription needed. (The older two-dose, half-tablets-12-hours-apart regimen has been replaced by the single dose, which works just as well and is easier to take correctly.)

How it works: it mainly delays or prevents ovulation for that cycle. If you take it before your body releases the hormone surge that triggers ovulation, the egg is not released and there is nothing for sperm to fertilise. This is why timing matters so much — once ovulation has already happened, the pill has little left to do. Importantly, it does not disturb a pregnancy that has already implanted and it is not an abortion pill; if you are already pregnant, it simply does nothing.

How well it works depends on how fast you take it. Roughly, it prevents about 85% of expected pregnancies if taken within 24 hours, around 75% at 24-48 hours, and about 60% at 49-72 hours. To put that in context, the chance of pregnancy from one act of unprotected sex during the fertile window is around 30%, so taking it early can cut that risk to roughly 4%. The lesson is plain: take it as soon as you can, ideally today, not tomorrow.

A note on body weight: some research suggests the levonorgestrel pill may work less well at higher body weight (often quoted above 70-80 kg or BMI over 25-30), though the data are mixed. Most guidelines still say take it rather than skip it, but if you weigh over 80 kg or have a higher BMI, the copper IUD is the more reliable option where you can access it.

Side effects are usually mild and short. You may feel nauseous (about 15-20% of women), tired, headachy, or have tender breasts or mild cramps for a day or two. If you vomit within 2 hours of taking the pill, take another dose — it may not have absorbed. Your next period may come a few days early, on time, or a little late, and may be lighter or heavier than usual. If it is more than a week late, take a pregnancy test.

Here is the option most Indian women are never told about: a copper IUD (Cu-T) inserted within 5 days of unprotected sex is the single most effective emergency contraception available, and it then keeps protecting you for up to 10 years. Most women default to the pill simply because no one offered them this.

How it works: copper ions create an environment in the uterus that is toxic to sperm, preventing fertilisation, and they also make the uterine lining unwelcoming to implantation. Because it acts on both fronts, it stays highly effective right through the 5-day window — even close to or just after ovulation, when the pill struggles.

How well it works: over 99% effective at preventing pregnancy from that exposure, and unlike the pill, effectiveness does not fade as the days pass within the window. It also works regardless of your body weight, which is a real advantage if BMI is a concern.

The catch is access. Insertion is a 10-15 minute procedure that needs a trained gynaecologist, family physician, or experienced ANM. Public facilities — district hospitals and well-equipped CHCs — can often fit in an emergency insertion if you come promptly, and it is free there. Private hospitals and clinics can usually see you within a day or two, costing roughly 300-2000 rupees, the same as a routine copper IUD insertion. Smaller PHCs and rural clinics may have less availability on short notice.

The payoff is two things from one visit: highly effective emergency cover now, plus a decade of contraception you do not have to think about again. If you have any interest in long-term contraception, it is worth specifically asking your provider about the copper IUD instead of automatically taking the pill. If you are weighing copper against the hormonal coil, our copper vs Mirena comparison goes deeper — note that the hormonal IUD is not used for emergency contraception.

Both are good options; they simply suit different situations. Here is how they line up.

Effectiveness. The copper IUD wins clearly: over 99%, versus 85% (at best, within 24 hours) falling to about 60% by 72 hours for the pill. For maximum protection — especially after 48 hours or at higher BMI — choose the IUD.

Deadline. The IUD gives you 5 days (120 hours) with effectiveness holding steady. The pill gives you 3 days (72 hours) and weakens by the hour. If it has already been more than 72 hours, the copper IUD is essentially your only effective option (unless ulipristal acetate, a more effective pill with a 5-day window, is available to you — it is not widely stocked in India).

Side effects. The pill brings a day or two of possible nausea, tiredness, or a headache — mild and brief. The IUD involves the insertion itself (cramping during and for a day or so after) and, for many users, heavier and more painful periods over the first 3-6 months that usually settle.

Access and speed. The pill is the runaway winner here — over the counter at any pharmacy, in your hands in minutes, 50-100 rupees. The IUD needs a clinic visit and a provider who can insert on short notice.

Cost over time. A pill is a one-off 50-100 rupees. The IUD is free to 2000 rupees but includes 10 years of contraception, making it far cheaper over time.

Ongoing protection. The pill covers only this one exposure; you still need a regular method. The IUD becomes your regular method for a decade.

The simple rule of thumb: if it has been under 72 hours, you can get the pill fast, and you already have reliable ongoing contraception, the pill is reasonable. If it has been more than 72 hours, your BMI is higher, or you would like to start long-term contraception anyway, the copper IUD is the better choice. For the full picture on the pill specifically, see our Indian guide to i-Pill and Unwanted-72.

Real scenarios make the choice clearer.

Condom broke a few hours ago, no other contraception, normal weight. Take the levonorgestrel pill straight away — it is about 85% effective in the first 24 hours and is the fastest, simplest option. Then plan your ongoing contraception.

Condom failed two days ago. The pill still works but at reduced strength (around 75% at 48 hours). If you can reach a clinic, the copper IUD offers higher protection now plus long-term cover — appealing if you would like to move on from condoms to something more reliable.

Missed pills, sex was four days ago. The pill is now at or beyond its useful window; the copper IUD is still well inside its 5-day window and remains highly effective. The IUD is the better choice. If you go this route, you would switch from your pills to relying on the IUD.

Higher BMI (say 32), sex 24 hours ago. The pill may be less reliable at higher body weight; the copper IUD works regardless of weight and is the safer bet.

Sexual assault, three days ago. You need more than emergency contraception — also STI testing and prophylaxis, possible HIV post-exposure prophylaxis if within 72 hours, emotional support, and the option of legal help. Most large Indian hospitals have a defined protocol for this; the next section covers it.

Already took the pill, but it has now been over 72 hours and you are worried. If you are still within 5 days of the exposure, a copper IUD can be added for extra protection (the two do not interfere with each other). Test for pregnancy if your period does not arrive within 3 weeks.

Sex was six days ago. Both windows have closed. Take a pregnancy test if your period is late, set up ongoing contraception, and keep emergency contraception on hand for next time.

The pill (i-Pill, Unwanted-72, and generics) is available without prescription at virtually every pharmacy — neighbourhood medical stores, market chemists, and chains like Apollo Pharmacy and MedPlus — for about 50-100 rupees. You ask for it by name, pay, and leave. Many women find the counter interaction awkward, and some pharmacists in conservative areas may comment or ask questions. If that worries you, larger chain pharmacies in cities tend to be more impersonal, and online pharmacies (Tata 1mg, PharmEasy, Netmeds) deliver — useful only if you have time to spare, since speed matters.

The copper IUD needs a clinic visit. The quickest access is usually a major private hospital (Apollo, Fortis, Cloudnine, Manipal, Max), where a same-day or next-day gynaecology appointment with insertion can often be arranged; book by phone or via apps like Practo. Cost is roughly 300-2000 rupees. Public district hospitals and larger CHCs offer it free — call the family planning department about availability. ASHA workers can point you to the nearest facility.

A few things that make the urgent moment less stressful:

After the pill. In the first day or two you may have mild nausea (15-20% of women), occasional vomiting, tiredness, a headache, breast tenderness, or light cramps. These pass within 1-3 days. Taking the pill with food can ease nausea. Remember: if you vomit within 2 hours of the dose, repeat it.

Your next period may arrive early, on time, or late, and may look a bit different from usual — lighter or heavier, shorter or longer. If it is more than a week later than expected, take a home pregnancy test (50-200 rupees at any pharmacy, reliable from about 2-3 weeks after the missed period). If you have had no period within 3 weeks of taking the pill, test. Our guide on confirming pregnancy after a missed period walks through the timing.

After a copper IUD insertion. Expect cramping for a day or two (manage with ibuprofen or similar), light spotting for up to a week, and a return to normal activity within a day or two. Over the first 3-6 months periods are often heavier and crampier, then usually settle into a steady pattern. A follow-up visit at 4-6 weeks confirms the IUD is sitting correctly.

Whichever method you used, if your period is significantly delayed or you have pregnancy symptoms, take a test and see a provider. Pregnancy despite emergency contraception is rare, but if it happens it needs checking — including ruling out an ectopic pregnancy, which is a medical emergency. Confirming that you are not pregnant is the final step before you can consider this episode closed.

Emergency contraception covers one exposure — it is a backup, not a routine method. Whether or not you need ongoing contraception going forward is worth thinking through soon after, ideally within a week or two.

If you used the pill and want to start a hormonal method, you usually can quickly. Combined birth control pills can begin the very next day, with condoms as backup for the first 7 days; the progestogen-only mini-pill similarly with 2 days of backup. The contraceptive patch or the vaginal ring can be started with your next period or via a quick-start approach.

For long-acting methods: a copper IUD can be inserted once pregnancy is ruled out — sometimes at the same visit. A contraceptive implant can go in immediately, and a DMPA injection can be given the same day with the standard 7-day backup. If you chose the copper IUD as your emergency contraception, you are already set for 10 years.

Prefer non-hormonal? Consistent condoms (typical-use failure 13-18%), the female condom, spermicides, or fertility-awareness methods are all options — each works best when you understand its limits and keep emergency contraception as a backup. And whatever you choose for pregnancy prevention, remember that condoms remain your main protection against STIs. If you are postpartum, our guide on when to restart contraception after birth covers what is safe while breastfeeding. If you are planning a pregnancy down the line, fertility returns quickly after stopping any of these methods.

The takeaway for the moment you are in: handle the immediate need first, then set aside time within a week or two for a fuller conversation about the method that fits your life.

After sexual assault, emergency contraception is one part of comprehensive care. The immediate needs include emergency contraception (copper IUD or pill within 72-120 hours), STI testing and prophylaxis for gonorrhoea, chlamydia and syphilis, HIV post-exposure prophylaxis if within 72 hours, tetanus cover for any injuries, emotional and psychological support, medical documentation, and the option of legal help if you choose to report. Most major Indian hospitals run a defined protocol, often through the emergency department or a one-stop crisis centre, and many districts have set up Sexual Assault Forensic Examination services. Throughout, every decision — whether to report, whether to pursue legal action, which medical steps to take — is yours.

Using emergency contraception more than once is safe when you need it. There is no fixed limit on how often you can take the levonorgestrel pill, and you can use it for repeated exposures. But it is not as effective as a method built for ongoing use, and frequent use can disrupt your bleeding pattern. If you find yourself needing it more than a few times a year, the real fix is reliable ongoing contraception — that would prevent most of the situations that send you back to emergency contraception in the first place.

For teenagers, the medical advice is identical to adults: emergency contraception is safe and appropriate after unprotected sex. The over-the-counter pill means a young woman can get it without involving a parent, though the counter experience can feel intimidating. Teens benefit especially from follow-up counselling on ongoing contraception and STI prevention — see our resource on comprehensive sex education for Indian teens. Where assault is involved, the comprehensive-care framework above applies, and POCSO and consent considerations may come into play depending on age and circumstances; India's family planning programme increasingly recognises the need for non-judgemental, adolescent-friendly services.

A lot of fear around emergency contraception comes from misinformation. Here is the truth on the most common myths.

"It causes an abortion." No. The levonorgestrel pill works by delaying or preventing ovulation; it has no effect on a pregnancy that has already implanted. The copper IUD prevents fertilisation and implantation but does not disturb an established pregnancy. Neither is an abortifacient — both prevent pregnancy from starting, which is medically and ethically different from ending one.

"It causes infertility." No. The pill has no lasting effect on your cycle or fertility beyond the cycle you take it in, and there is no cumulative harm from using it multiple times. The copper IUD is fully reversible — fertility returns quickly once it is removed.

"It's dangerous." No. The pill has mild, brief side effects and an excellent long-term safety record. The IUD has insertion discomfort and heavier early periods but a long, well-established safety profile.

"You can use it as your regular birth control." No. It is designed for occasional backup, is less effective than dedicated ongoing methods, and side effects mount with frequent use. If you need it often, switch to a regular method.

"It works no matter when you take it." No. Both are time-sensitive — the pill drops from ~85% at 24 hours to ~60% at 72 hours, and the copper IUD only works up to 5 days. Sooner is always better.

"It's the same as the abortion pill." No. The abortion pill (mifepristone with misoprostol) ends an established pregnancy under medical supervision. Emergency contraception is used beforehand to stop pregnancy from happening. For your legal rights around both, see abortion rights in India.
